PVC Pull String Pop Up Hidden Surprise Puzzle GeoCache

Description

The Cache is hidden inside, and revealed via a Pull-String.
See it work, here: https://youtu.be/NqG2yOwGPBk (this one is the same, but smaller, than the monstrosity in the video)
Cost Note: This is an expensive Cache to build. It's also large and heavy. All my prices are as reasonable as possible. Thanks for understanding.
